How do you know if you have an exposed tooth nerve?

I am a 28 year old male. I wonder how can I know if I have an exposed tooth nerve?

Signs like hot sensation for more than 3 seconds.
There are a few reasons why someone would have an exposed "nerve", but an exposed "nerve" that is still alive would become extremely painful to cold, acidic foods, and pressure. Once a "nerve" becomes infected it will usually become more painful when the tooth is exposed to heat and or pressure, the pain would linger and or throb, mostly at nigh time. An exposed "nerve" that is not treated ASAP is more likely to become infected, and the treatment can become more difficult and expensive.
Hello,

Having recently exposed dental nerve is usually something that makes people visit the dentist. There is a nerve and blood vessels inside each tooth. The nerve can get injured in a variety of ways all resulting in the same event; discomfort of some sort. Diagnosing an exposed nerve is a matter of understanding the presenting symptoms, clinical evaluation, and level of discomfort. As a cavity gets larger, it grows closer to the blood vessels and nerve. The blood vessels swell up and put pressure on the nerve. This sends pain signals back to the brain. As the cavity gets larger, the tooth starts to break down around the nerve and then the nerve is exposed to anything in the oral cavity. Once this happens, the nerve is irritated by everything. However, since this usually takes time the nerve starts dying before the nerve is fully exposed. Sometimes the tooth can break before the nerve gets injured. This is a very painful condition. Usually people describe it as something that makes them jump through the roof and seek out professional care.
Hope this helps.

My best to you!

Hello,

If the nerve is actually exposed you will need either a root canal or extraction. Some rare other possibilities, but with also low success rates for treatment. As far as you knowing.... you wouldn’t most likely. Relatively impossible to visually see... and only if it’s on a front tooth and only a strange circumstance that would allow “you” to see the nerve. You would need an X-ray/3D view or dentist to see.
Very simply put: PAIN
You will experience pain and/or swelling. Pain can be spontaneous or while eating.

It depends on many factors. How long have you experiencing the pain? Is the tooth fractured? Is the tooth infected? You can experience from extreme pain (Acute) to constant dull pain (Chronic). Cold is usually a pain trigger for any exposed nerve. Please visit your dentist for a definitive diagnosis. Good luck, hope you feel better soon.
